Concept Introduction:
(b)
Interpretation:
The unit for the rate constant of a zero-order reaction should be stated.
Concept Introduction:
Rate of reaction represents the change of concentration of a reactant or a product with respect to time. It can be expressed either by reduce amount of reactant in per unit time or increase amount of product in per unit time.
(c)
Interpretation:
The unit for the rate constant of a first-order reaction should be stated.

Chemical Principles
- Rate law experiments dont always give data in the form of a rate in moles per second. Some of them give an amount of time necessary for a reaction to proceed to a given point. The faster the rate, the less time necessary. For the following data, assume that the time given is to react 0.10M of A. Determining the complete rate law for the reaction A+Bproducts. Time taken (s) [A] [B] 36.8 0.20 0.40 25.0 0.20 0.60 10.0 0.50 0.60 A classic chemical reaction/demonstration called the iodine clock reaction is usually measured this way.arrow_forward. find the rate law predicted for a particular reaction mechanism.arrow_forwardExplain how a species might be part of a rate law but not part of a balanced chemical reaction.arrow_forward
- Define these terms: (a) unimolecular reaction (b) bimolecular reaction (c) elementary reaction (d) overall reactionarrow_forwardThe type of rate law for a reaction, either the differential rate law or the integrated rate law, is usually determined by which data is easiest to collect. Explain.arrow_forwardThe rate law for a reaction can be determined only from experiment and not from the balanced equation. Two experimental procedures were outlined in Chapter 11. What are these two procedures? Explain how each method is used to determine rate laws.arrow_forward
- If the reaction:A+BC+D is designated as first order, the rate depends on: a.the concentration of only one reactant. b.the concentration of each reactant. c.no specific concentration. d.the temperature only.arrow_forward. Account for the increase in reaction rate brought about by a catalyst.arrow_forwardFor this reaction mechanism, write the chemical equation for the overall reaction. write the rate law for the reaction. is there a catalyst involved in this reaction? If so, what is it? identify all intermediates in the reaction. draw a reaction energy diagram for the reaction.arrow_forward
- use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.arrow_forwardFor the reaction of phenyl acetate with water the concentration as a function of time was given in Question 11. Assume that the concentration of water does not change during the reaction. Analyze the data from Question 11 to determine (a) the rate law. (b) the order of the reaction with respect to phenyl acetate. (c) the rate constant. (d) the rate of reaction when the concentration of phenyl acetate is 0.10 mol/L (assuming that the concentration of water is the same as in the experiments in the table in Question 11).arrow_forwardCobra venom helps the snake secure food by binding to acetylcholine receptors on the diaphragm of a bite victim, leading to the loss of function of the diaphragm muscle tissue and eventually death. In order to develop more potent antivenins, scientists have studied what happens to the toxin once it has bound the acetylcholine receptors. They have found that the toxin is released from the receptor in a process that can be described by the rate law Rate = k [acetylcholine receptortoxin complex] If the activation energy of this reaction at 37.0C is 26.2 kJ/mol and A = 0.850 s1. what is the rate of reaction if you have a 0.200M solution of receptor-toxin complex at 37.0C?arrow_forward
